In the isolated coastal town of Wirramurra Bay, where salt winds carry secrets across limestone cliffs and drought has left the landscape bone-dry, Detective Jodi Brennan arrives for what should be a punishment posting.

What begins as the apparent suicide of veterinarian Dr. Sarah Kellerman evolves into something far more sinister, revealing connections between livestock poisoning and powerful corporate interests operating in the shadows of rural Australia. When Jodi discovers that Sarah was investigating environmental contamination targeting vulnerable farming families, she must navigate both bureaucratic resistance and escalating threats from those who profit from silence.

As her investigation deepens, Jodi uncovers links between Sarah's murder and a sophisticated scheme to acquire valuable farmland through deliberate contamination. With federal corruption reaching into the highest levels of government, each revelation tests Jodi's determination and puts her understanding of justice to the ultimate test.

The vast Southern Ocean coastline conceals corporate greed and environmental destruction, where millions of dollars are at stake. But in a country where ancient limestone holds both water and secrets, some truths refuse to stay buried.

Jodi must rely on her detective instincts and the trust of a close-knit community to read the signs before more lives are lost, all while confronting forces that view both land and people as expendable resources.
